This is a rather interesting Canon patent application, and it might well go into production…
Here is a Canon patent application for a new EVF (Electronic ViewFinder) for a mirrorless camera. Folded optics are employed.
Canon patent application 2020-95073A (Japan) discusses a new kind of Electronic Viewfinder featuring folded optics, a technology used for smartphone camera lenses and everywhere you want to have an optical path that’s longer than the size of the system. Prismatic binoculars being a good example.
The EVF in the patent literature uses polarized surfaces to maximize reflection. We think this patent might go into production, sooner or later. The patent application was spotted by Hi Lows Note.
